Be it known that I, HENRY A. RosBAoK, a citizen of the United. States, anda resident of Chicago, in the county of Cook and State of Illinois, haveinvented. certain new and use,- ful Improvements'in ailway-Switches, of which the following is a clear, full, and exact Myinvention relates I to railway-switches and its object is to dispense with frogs and to make a switch which when once thrown will keep the rails securely locked, so that it can not vibrate to suchan extent whena train I passes over the switch as to throw the switch- I I ever or-break-the connections therewith, as

, is sometimes I done 'with the switch-levers tinuous switch-railO, split in t now in use, and which can be set to provide either a continuous mam track or a continuous switch-track. This I accomplish by the I means hereinafter fully described andas particularly pointed out in the claims.

Inthe drawings, Figure 1 is a plan View of my invention. Fig. :2 is a similar view of a modified form, thereof. Fig. 3 is a detail view showing a transverse section of the pivot of the rail and tie supporting the same.

In the drawings, A represents the continu ous straight rail ofthe main track B, the short length of the straight rail of the main track; C, the continuous curved rail ofthe switch, and D'repr'esents the short length of the curved ;rail of the 1 switch. The short straight rail B and short switch-rail D are brought together and, their ends cut and .joined'to form apoint a. Between this point and the transverseplane of the lace Where, the continuous curved, rail C o the switch merges into the main track the'movable raile sections of the switch are located These consist of a movable main-track section of rail E, whichwhen the switch is closed alines with the short straight rail B, and the movable curved switch-section-of railE, which when theswitch is open forms a continuation of the short, curved switch-rail D. The rail E has its end portion, which en ages the confie usual manner, and so likewise is the adjacent end of the movable switch-section of rail F split to engage the continuous straight rail A of the main track. Both rails E and F are secured to the ties was near their opposite ends in such manner that their split ends have the'necessary spring to them to move in and out of engagement with the continuous rails, and at r Specification of Letters Patent.

'their opposite ends, which are but a short dist; I I tance removed from point -a, theyeach have pivotally connected thereto the-extensions be;

Extension 1) of the movable main-track sec- I I tion E issoshapedorbent that when the switch is closed it extends to point ain aline-5 ment' with rail B and is then deflected; at;

such an angle that a part of itslengthwill be I parallel to and engage rail Don one side of pointa and its extremityfarthest from its pivot is turned at an angle obliquely away from saidrail, D. Extension 0 isshaped or bent in the same manner as extension I), but I v in the opposite directionand so that when V .7

the switch is open it will betweenitspivoted end and point a aline with'rail D, and there-1 mainder of its length, except its oflsetextremity farthest from the pivoted end," w1ll 'be parallel to and bear against rail B.

The split ends of rails E and E are eeh f cross-bar. d and are placed such a distance vice versa, and when said rail E engages railfC is nected together in any suitablemanner byja I I 1 the extension 1) thereof will be inenga ement with point a' and a continuous throug main track will be provided, and extension 0 will be out of engagementwith said point; When; 7 however, rail F en ages rail A, theextension c of said railF will engage point a, and ex-. tension .7) will be moved out offengagement therewith, and a continuous through switchmovements of the rails E, and F and their ex-f track will beprovided. I accomplish the,

tensions in the manner 'just described :by

'means of a T-shaped bell-crank G, whichv is suitably pivoted between rails A and about opposite the centers oflength of railsv E and]? and connected to the end of the longitudinallyI-disposed. intermediate arm ofthe, bell-crank G by a [shifting bar 6 to a switchg 4 lever H of any suitable type. The aliningj:

transverse arms of the bell-crank are con-,1

nected one by a connecting rod orbar f to the knee of a toggle-joint g, theouter ex tremity of one link of which is pivotally connected to the extension I; and the outerex- Ii I tremity of the otherlink of which is, ful

c. The other alining armvof the bell-crank"; I

crumedto the tie at or bya suitable lug toraili is connected by a. c'onnecting-rod h toa; tog- ,gle-joint j, the extremity ofone arm of which I I I V I is pivotally connected to extension 0 and the,

opposite end ofthe other arm of whichis pro- L T 1 vided with a stationary fulcrum secured eith'erto. the tie or directly or indirectly to the rail A.

The arm of the bell-crank to which rod his connected has a rod k connected thereto and extending in a direction opposite therefrom to a point between the split ends of movable rails E and F, where it is connected to the knee of a toggle-joint I. One 'end of one of the links of this joint I is connected to rail E and the opposite end to a tie 90. When the bell crank is moved to the position shown in Fig. l of the'drawings, to gle-joints g and I will be straightened to ma e'the main track continuous, and toggle-joint j will be'bent. When the'bell-crank 1s moved to the position shown in dotted lines in said Fig. 1, togglejoints 9 and I will be bent, and toggle-joint will bestraightened to open the switch and provide a continuous switch-track. The use of these toggle-joints secures the rails of the track rigidly in the position desired, and the shock and concussion of a train moving fast over the same will not vibrate them or communicate vibrations throu h them to the switch-lever mechanism and throw it involunt'arilyoutof position to permit any change of position'of the rails.

In Fig. 2 of thedrawings I show a modified form" of my invention which consistsin making'the movable main-track rail J and the movable'switch-"rail K op osite the split ends thereof with integral en sm n, which take the place of the pivoted extensions 1) c of my invention, as shown in Fig. 1 of the'drawings, and perform the same functions. In their modified form the movable rails 'J and K are secured to the'ties at'about their centers of length, and'both their split ends andtheir ends mm, which alternately engage point a, are made to possess a certain amount of spring, whereby through the medium of the toggle-joints g it they are made to perform thesam'e functions as said pivoted extensions 1) c. I desire to be considered as contemplatingfboth of these forms of movable rails as coming within the scope of my invention.

I do not wish to be confined to any particular means for pivoting the end of the extension's b c to the rails E and F. I prefer, however, to employ the means shown in Fig. 3 of the drawings, in which the tie a: isprovided with a plate 2, that has a socket 3 mediate its ends'for the pivotal stud 4 of a chair 5, in

which the flange of the end extension-rail is suitably secured. As stated, however, other means for pivoting the ends of the extensions may be employed, if desired.
